@Kevitec57 Totally agreed and thanks for the suggestion. I neglected to add that registry edits should come with a word of caution and usually as a last resort. The icon issue I inadvertently created impacted the app at a global level, including any prior or new projects. But the answer was already here in the above thread, just needed to look harder.
